Jag3D - What about 3d projection reduction? (Software)

Hi Micha,

I thought I could ask you a question here, as the answer may be interesting for other people.

I was wondering why the projection option 3d reduction had disappeared in the newer versions, while it was integrated in v3.5.20170423 for example. I see that instead, you have integrated vertical deviation correction, but is there any tool in JAG3d that can help us to calculate a vertical deviation model? (spherical for instance)?

Thank you anyway for the great work you've achieved.

Hello,

This module war replaced by a more rigorous mathematical model, i.e. the deviation of the vertical can now be estimated within the adjustment process. Using the current version of JAG3D, you can estimate the position [x/y/z] as well as both vertical deviation angles. You have to enable the option "Consider deflection of the vertical", see screenshot. In most cases, the deflection of the vertical can only be estimated for station points, especially, if target points haven't an instrument height.
